Features
|
|
 |
nano silica 60, specific surface (BET) ~ 500 m2/g, mean pore size 60 Å, specific pore volume 0.75 ml/g, particle size 2 – 10 µm
very
thin nano silica layer for the AMD procedure (automated multiple
development), which allows rapid and efficient simultaneous analyses of
several active ingredients at ultra trace levels
available as glass plates with fluorescent indicator |
|
An interesting TLC method is the PMD technique (Programmed Multiple Development) [K. Burger, Fresenius Z. Anal. Chem. 318 (1984) 228 – 233],
which is a true gradient development on silica for TLC. Contrary to the
common multiple development every single run is slightly longer than
the previous one. Thus broadening of substance zones during
chromatography is easily compensated for. Usually, about 10 to 25
development cycles are run, generally with a universal gradient. Since
this technique can be automated, you can also find the name AMD
(Automated Multiple Development) [K. Burger, Pflanzenschutz-Nachrichten Bayer 41,2 (1988) 173]. |
